## Critique

Critique is built on a simple observation: people form beliefs while scrolling, but verification usually happens somewhere else entirely. The extension closes that gap by attaching critiques directly to the content in your feed. Claims that appear in Reddit threads, YouTube comments, X posts, LinkedIn, BlueSky and Threads are automatically cross-referenced and annotated, with reliability scores and sources shown inline so you can judge a claim without leaving the page.

Beyond the feed, Critique works as an on-demand research companion. Right-clicking any text on any website sends it for verification or asks a question about it, and its Critique Flow feature lets you add browser tabs to a prompt so the model reasons over your actual open pages rather than a stale training snapshot. Responses carry citation-style annotations so you can trace where an answer came from.

The project is developed by Starman LLC and offers a free tier, with an iOS and Android app listed as coming soon behind a waitlist. It has a public Discord community for sharing critiques and getting support, and it maintains a blog discussing misinformation as a computational problem.

**Pricing & Plans:** Freemium with a free tier; the browser extension is available to add and use at no stated cost. Mobile apps are announced as upcoming with a waitlist. Refer to the site's pricing page for the current breakdown of any paid tiers.

- **Automatic inline critiques:** Fact-check annotations appear unprompted on comments and posts across Reddit, YouTube, X, LinkedIn, BlueSky and Threads.
- **Right-click verification:** Select any text on any website and get it vetted or ask a follow-up question without leaving the page.
- **Critique Flow:** Add open browser tabs to a prompt for cited, up-to-date answers grounded in what you are actually reading.
- **Reliability scoring:** Each critique surfaces how credible a claim or source is, so you can weigh information at a glance.
- **Chat with web pages:** Ask questions about articles and get answers annotated with the sources they came from.

**Strengths:** Works inside the platforms where misinformation actually spreads; Critiques are automatic, so verification needs no extra effort or tabs; Cited answers make it possible to trace where a verdict came from; Free to install and use via the browser extension

**Limitations:** Annotated verdicts should still be treated as a starting point rather than a final authority; Automatic critiques depend on platform page structures that can change; Mobile apps are not yet released, so phone browsing is less covered

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
